本回答被网友采纳worth， worthy， worthwhile 这三个词均可表示“值得的”，由于它们词形相近，意义相似，所以许多同学经常将其用混。它们的用法区别：
一、从句法功能上看
从句法功能上看worth 通常只用作表语，不用于名词前作定语;worthy 和 worthwhile 可用作表语和定语。如：It isn‘t worth the trouble. 不值得费那个事。He is a worthy gentleman. 他是位值得尊敬的绅士。他是位值得尊敬的绅士。His behavior is worthy of great praise. 他的行为值得高度赞扬。They achieved a very worthwhile result. 他们取得了很有价值的成果。
We had a long wait， but it was worthwhile because we got the tickets. 我们等了很久，但还算值得，因为我们把票买到了。
二、从所使用的修饰语来看
worth 习惯上不用 very 修饰(要表示类似意思可用 well)，而 worthy 和 worthwhile 则可以用副词very修饰。如：veryThat is very worthy of our attention. 那件事很值得我们注意。Nursing is a very worthwhile career. 护理工作是很值得干的职业。但习惯上不说：The work is very worth doing. (very 应改为 well)。
三、从搭配习惯来看
有关 be worth 的搭配习惯
(1) be worth后可直接跟名词、代词或动名词。如：The picture is worth $ 500. 这幅画值500 美元。The clock is hardly worth repairing. 这台钟简直不值得修理。What is worth doing is worth doing well. 值得干的事就得干好。注意：其后可接动名词，不能接不定式，且接动名词时，总是用主动形式表示被动意义。
(2) 在现代英语中，在be worth前使用形式主语it被认为是合习惯的。如：It isn‘t worth repairing the car. 这辆汽车不值得修了。Is it worth visiting the city? 这个城市值得去看吗? 但是，若不用形式主语it而直接用动名词作主语则是错误的，如：误：Repairing the car is worth.
(3) 在be worth doing 结构中，除非句首用了形式主语it，否则句子主语总应是其动名词的逻辑宾语;若其中的动词不及物，应考虑加上适当的介词。如：Nothing he said was worth listening to. 他说的话没有一句值得听。She’s not worth getting angry with. 犯不上跟她生气。
2. 有关 be worthy 的搭配习惯
(1) be worthy 后不能直接跟名词、代词或动名词，若要接，应借助介词 of.如：Their efforts are worthy of your support. 他们的努力应得到你的支持。 Her behavior is worthy of praise. 她的行为是值得赞扬的。
(2) 与be worth后只接动名词不接不定式不同，be worthy后不接动名词，而接不定式(若该不定式要表示被动意义，则应用被动形式)。如：He is worthy to receive such honor. 他应该得到这种荣誉。FONT-FAMILY： 'Times New Roman'">This suggestion is worthy to be considered. 这个建议值得考虑。
(3) 若要在be worthy后接动名词，与后接名词时的情形一样，应借助介词of，且该动名词若要表示被动意义，要用被动形式。如：He is worthy of filling [=to fill] the post. 这个职位他当之无愧。This suggestion is worthy of being considered [=to be considered]. 这个建议值得考虑。
3. 有关 be worthwhile 的搭配习惯的搭配习惯
(1) be worthwhile 后接动名词或不定式均可。如：It is worthwhile buying the dictionary. 这本词典值得买。(其中的 worthwhile 也可换成 worth)It is worthwhile to discuss the plan again. 这个计划值得再讨论一次。(n'">这个计划值得再讨论一次。 worthwhile 不能换成 worth，因为其后接用了不定式)
(2) 有时可将worthwhile分开写，此时也可在其中加上one‘s.如：I’d think it worth while to go. 我认为值得去。

1. worth是一个只能作表语的形容词，意思为“值……的”、“相当于……的价值的”、“有……价值的”、“值得……的”。后接名词、接动名词的主动形式。例如：
This second-hand car is worth $2000 at the most.
The exhibition is worth a visit/visiting.
It’s not worth getting angry with him.
The question is not worth discussing again and again.
2. worthy可作表语，也可作定语。作定语时意思为“有价值的”、“值得尊敬的”、“应受到赏识的”；用作表语时意思为“值得……的”、“应得到……的”，其后接of sth.，也可以后接to do sth.，例如：
①That is worthy of note. 那件事值得注意。
②This phenomenon is worthy of being studied. 这种现象值得研究。
③This problem is worthy to be considered. 这个问题值得考虑。
④The film is worthy to be seen again. 这部电影值得再看一遍。
⑤This is a worthy English-Chinese dictionary. 这是一本有价值的英汉词典。
⑥This is a worthy article. 这是一篇值得一看的文章。
⑦He said he was not worthy to accept such honour
⑧The school has educated many worthy young people.
⑨The question is not worthy to be discussed again and again.
作后置定语时，必须用“worthy of +名词”结构。例如：
⑩There is nothing worthy of mention. 没有值得一提的事情。
②This is behavior worthy of praise. 这是值得称赞的行为。
③ Something find and rare --- something worthy of the honor of being owned by Jim.
(S3 Unit 10 P84)
注：“worthy of+动名词”与“worth+动名词”在形式上完全不同：worthy of后面接被动式的动名词；而worth后面接主动式的动名词，虽然在形式上是主动的，但其意义仍然是被动的。试比较：
The second-hand house is worthy of being bought. = The second-hand house is worth buying.
3. worthwhile与worthy一样，既可作表语，又可作定语。表示某事因重要、有趣或受益大而值得花时间、金钱或努力去做，一般做“值得的”、“值得做的”、“有意义的”解。用作表语时，可接动名词或动词不定式。例如：
